 Brief Description: A tornado damaged 2 homes, several farm buildings, and 2 steel grain bins as it struck 10 miles north and 2 miles east of Greenbush. One man barely made it out of his trailer home before the tornado struck. As the tornado travelled between the 2 homes, it came close to a tractor plowing a field. A man in the tractor had glass blown into his eyes as the glass tractor cab shattered. A third home, 3 miles east and 2 miles north of Greenbush, was shifted off its foundation as the tornado passed. The tornado crossed highway 11, damaging a fourth home located 3 miles east of Greenbush, before dissipating.

 Brief Description: EVENT NARRATIVE: This tornado began in Polk County, about 4 miles south-southwest of Mentor at 615 PM CDT. The tornado tracked into Red Lake County and continued an additional 6 miles to roughly 4 miles east-northeast of Terrebonne. The tornado sheared trees and blew down farm buildings near the Polk County line and lofted debris from Mentor well past the community of Plummer. The total track length was about 15 miles and peak winds were estimated at 145 mph. EPISODE NARRATIVE: Conditions were ripe by the afternoon of the 17th for a major severe weather outbreak. A surface low had moved into east central North Dakota with an occluded front extending to the southeast. Warm and humid air was in place ahead of the front, with a much drier airmass pushing in behind it. The 500mb low was located over northwest North Dakota with a nice southwest to northeast upper jet pushing into eastern North Dakota. Two lines of convection formed by late afternoon, one from Roseau County down toward Eastern Otter Tail County and the other over east central North Dakota. Nearly all the cells that formed took on a classic hook shape with rotation very evident on radar imagery. Multiple tornado warnings were issued before the event wound down by mid evening. The strongest tornadoes were determined to be EF4 tornadoes, two in west central Minnesota and one in northeast North Dakota.

 Brief Description: Tornado number two of a series tracked east-southeast for about 4 miles across the northern part of Warroad. The main tornado appeared to have touched down about a mile west of the Marvin Windows plant complex at the northwest corner of Warroad. The tornado grew to around 500 yards wide as it moved across the Lakeview Park and campground area. The tornado apparently lifted as it passed into Muskeg Bay of the Lake of the Woods. Peak wind speeds were estimated from 160 to 180 mph. Damage was extensive along the tornado path in Warroad. At the Marvin Windows plant, the roof was damaged and 16 semi trailers were overturned. Several of the trailers were full with new windows, which were a complete loss. The nearby Pepsi plant had its sign blown down. At the Warroad City Park and Campground, 30 to 40 campers were destroyed and roughly 10 boats were damaged or sunk. The city pool, which had been recently renovated, was also damaged. The Trading Post Gift Shop was completely destroyed. Many large trees were also snapped off or broken into pieces. Eight to 10 homes also sustained damage.
